Listen "Ego Depletion Theory (Baumeister)"

Episode Synopsis

We explore the concept of ego depletion, a theory positing that self-control is a limited resource that diminishes with use, impacting subsequent self-regulatory efforts. The articles examine the theory's supporting evidence and critiques, including the role of motivation and the impact of depletion on various behaviours such as eating, spending, and social interactions. Debate surrounds the robustness of the ego depletion effect, with some research suggesting its influence is smaller than initially believed, potentially due to methodological issues and publication bias. However, the texts also explore potential biological underpinnings, like glucose levels, and the moderating role of motivation in self-control success or failure. Ultimately, the sources highlight the ongoing discussion around the nature and limits of self-control.
